Law of equipartition of energy

Question

Directions (Q. Nos. 1-4) These questions consists of two statements each printed as Assertion and Reason. While
answering these questions you are required to choose any one of the following four responses.
Assertion : Degree of freedom of a monoatomic gas is always three, whether we consider vibrational effects or not.
Reason : At all temperatures (low or high), vibrational kinetic energy of an ideal gas is zero.

Moderate

A

If both Assertion and Reason are correct and Reason is the correct explanation of Assertion.
B

If both Assertion and Reason are correct but Reason is not the correct explanation of Assertion.
C

If Assertion is correct but Reason is incorrect.
D

If Assertion is incorrect but Reason is correct.

Solution

In ideal gases, there is no inter-particle interaction. So, no vibrational energy is there.
$∴$ Only the kinetic energy contribute to the internal energy.Mnoatomic gas molecules have only translational kinetic energy which has three degrees of freedom .
